Answer:
Height of the object is 68.6 cm.
Step-by-step explanation:
The height of the object can be determined by:
=
From the given question;
object distance from pinhole = 3.6 m = 360 cm
image distance from pinhole = 4.2 cm
height of image = 0.8 cm
So that;
=
⇒ object height =
=
= 68.571
object height = 68.6 cm
Thus, the height of the object is 68.6 cm.
